KB37 not working after upgrading hardware in PC

Hello! I've got this KB37 that used to work just fine, my processor died on me so I had to upgrade it, after the upgrade, haven't been able to make it work. I tried reinstalling drivers and the licensing, it just won't recognize it so I can't do any firmware updates.

When I plug it in it sounds as something connected, but it never recognizes the keyboard. Any suggestions on what to try?

In my case it does even disable all the sound from my computer. After reinstalling my computr is completely quiet both in on board card and on KB37. Unpluging KB37 doesnt start onboard sound. Windows say sound has been disabled, When i check in control panel it says both onboard card and KB37 are set to "standard" even it both ar disabled. This is catch 22. And I have a soundtrack to make to a video......
